Specification of Letters Patent.

Patented June '7, 1921.

Application filed April 14, 1920. Serial No. 373,875.

To all whom it may concern:

Be it known that I, AKsEL THEoDoR' JES- PERSEN, a citizen of the'IInited States, and a resident of Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Wedges, of which the following is a specifi-' cation.

My invention relates to wedges more particularly adapted for the splitting of logs, and a purpose of my invention is the provision of a wedge of this character which is of simple and eflicient construction and which is capable of effecting a greater degree of splitting than wedges heretofore proposed. v

I will describe one form of wedge embodying my invention and will then point out the novel features thereof in claims.

In the accompanying drawings:

Figure 1 is a view showing in perspective one form of wedge embodying my invention with the parts thereof partly assembled.

Fig. 2 is a view showing in front elevation the main section of the wedge in working position within a log.

Fig. 3 is a view similar to Fig. 2 with the complete wedge in working position.

Fig. 4.- is a transverse sectional view taken on the line 4-4 of Fig. 1.

Similar reference characters refer to similar parts in each of the several views.

Referring specifically to the drawings and particularly to Fig. 1, M designates the main section of a wedge which is slotted for a major portion of its length as at 15 to provide parallel members 16 and 16 The parallel members 16 and 16 are integrally connected at their lower ends by a ointed portion 17 The pointed portion 1 as well as the sides of the portions 16 and .16 are in clined so as to simulate the contour of a wedge. The confronting sides of the portions 16' and 16" are formed with tongues 18 and 18*.which are coextensive in length with such portions.

A designates an auxiliary section which is adapted to be used in conjunction with the main section M. The auxiliary section A is substantially triangular in formation and is provided at its opposite sides with grooves 19 of a contour corresponding to the tongues 18 and 18 so as to receive the latter and to thereby support the auxiliary section in right angular position with respect to the maln section. The auxiliary section A is provided at its upper end with a recess 20, the vertical walls of which are provided with tongues 21.

In conjunction with both the main section M and the auxiliary section A, a head designated generally at II is adapted to be used and serves as an anvil for such sections on which the wedge is to be struck by a hammer or other suitable tool. As shown in Figs. 1 and 3, the headHis of T-shaped formation, the vertical portion of which is provlded at its opposite sides with vertically extending grooves 22 that are adapted to recelve the tongues 21 of the auxiliary sect on A in the manner clearly illustrated in Flg. 1. The head H is also applicable to the main section M as shown in Fig. 2, and when in this position the grooves 22 of the head receive the tongues 18 and 18' with the vertical portion of the head interposed between the members 16 and 16 In practice, the head II is associated with the main section M and the latter is driven into the log by striking the head H with a hammer or other suitable tool. After the main section M has been driven substan tially its full length into the log, the head H is removed and the auxiliary section A is then inserted into the main section M in the manner shown in Fig. 1. The head II is now applied to the upper end of the auxiliary section A so that when the latter is now struck, the auxiliary section'is forced into the opening in the log previously formed by the main section M. After the auxiliary section has been driven into abutting relation with the free end of the main section, the two sections will then move downwardly as a unit to effect a further splitting of the log. As the auxiliary section is disposed at right angles to the main section, it will be manifest that a much greater spread of the log can be effected than is possible with the ordinary wedge. It will be further noted that because of the formation of the sections comprising the wedge less force is necessary in driving the wedge into a piece of wood.

Although I have herein shown and described only one form of wedge embodying my invention, it is to be understood that various changes and modifications may be made herein Without departing from the spirit of the invention and the spirit and 2. A Wedge comprising, a main section,

an auxiliary section sliclable on the main section and disposed at right angles thereto,

and a head section attachable to the main section at right angles thereto and to the auxiliary section in the same plane as said section.

8. A Wedge comprising, a main section, an auxiliary section disposed at right angles to the main section and detachably associated therewith, and a head attachable to either of the sections.

4. A Wedge comprising, a main section, and an auxiliary section slidable on the main section and disposed at right angles thereto.

5. A Wedge comprising, a main section, an auxiliary section slidably mounted on the main section, and a head applicable to either of the sections.

6. A Wedge comprising a main section, an auxiliary section having a tongue and groove connection With the main section and disposed at right angles thereto, and a head having a tongue and groove connection With either of said sections.
